Application filed December 18, 1917.

` To all whom t may concern:

Be it known that I, JERRY W. CAMMAGK, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Toys, of which the following is a specification.

This invention is a toy which consists of a car, other vehicle, or the like so constructed as to be self-returning. In other words, when propelled in one direction by either pushing or pulling, the same will automatically travel in the reverse direction by reason of tension applied to a resilient member while traveling in the first-mentioned direction.

In the accompanying drawings forming part of this specification and in which like numbers of reference denote like parts wherever they occur,

Figure l is a side elevation;

Fig. 2 is a longitudinal sectional view showing the parts in initial position;

Fig. 3 is a longitudinal sectional view showing the resilient locomotor means stretched and the cords partly wrapped around the axles after partial travel in one direction;

Fig. 4; is a sectional view on the line 4 4 in Fig. l, looking in the direction of the arrows; and

Fig. 5 is a fragmentary sectional view of one 0f the wheels.

The car l may be of any desired construction, and is slotted at 2 to receive opposite ends of the axles 3, which revolve with wheels 4, there being as many axles and accompanying wheels as are deemed proper.

Each wheel is encircled by a resilient or other friction-making band 5, in order the more readily to grip the floor or other surface on which the car is to travel, which band 5 may be composed of a strip of felt, cloth, or a wind or winds of twine or of any other suitable material.

The movement of the car 1 forward causes the cord 6 and elastic strip 7 or similar resilient material (or in some instances only the cord 6) to wind on one of the axles 3, which has the effect of storing energy in the spring or resilient member 7 (preferably formed of an elastic strip, as above stated).

Cessation of movement forward leaves the car free to return in the opposite direction, which return begins as soon as the force- Specifcation of Letters Patent. f

impelling forward movement ceases, the return movement being caused and continued by the release of the energy stored in the elastic member 7. In its return movement, the cord 6 unwinds on the axle, but does not store resilient energy, but is merely dropped out of the way on bottom or floor 8.

Ordinarily the forward movement will be caused by the hand pressing upon thetop of the car so as to produce suficient frictional contact between the wheels and the Hoor to revolve the wheels and their axles while at the same time a forward shove will be given to the car until adequate momentum has been imparted to it to carry it a considerable distance, thus tensioning the spring member 7. When friction on the floor, inertia, and the pull of member 7 has resulted in stopping the forward progress of the car, it is then ready to return, as hereinabove stated.

The U-shaped slots 2 form a simple and commodious journal for the axles 8, and the said axles 3 are held in the U-shaped journals or slots 2 by the bottom 8 of the car l, which is attached by nails or screws 9 in an easy and convenient manner. It will be noted that this way of holding the axles in their simple journals is a particularly cheap and effective construction and that the simple spring member makes it likewise possible to construct the entire toy at a very low cost, which is a desirable and necessary feature in such an article.

The motive parts, except the wheels, are neatly inclosed within the construction provided by the body proper and the bottom.

At the end of the resilient member 7 opposite to cord 6 is preferably another cord 10, by which it is fastened to floor 8 or to the end of the car or any other suitable place by a screw 11 or staple or in any other manner.

Either of the axles may be usedfor athaving U-shaped cuts adapted kto form a. bearing'foi- 4Said miles; afbOt-toni secured t0 part-,momentum t0 one of Said axles and its Wheels, means eii'ectln'g connection between one' end Oise/1d resillent member-and a p'olnt signature. Y
